Project preparation and catalytic funding facilities

Most climate and infrastructure projects stall before they reach a lender: there is no money for feasibility studies, environmental and social assessments, legal structuring or the first risky equity. Project preparation facilities and catalytic funds exist to pay for that stage.

This guide is for developers and sponsors in developing countries, and for international developers, engineering firms and advisors based in developed countries who are preparing projects abroad. It separates facilities that accept applications directly from those that only work through governments or partner banks, and explains how to build an application that passes screening.

What project preparation money pays for

Preparation funding covers the work that turns an idea into a project a lender can assess:

  • Pre-feasibility and feasibility studies.
  • Environmental and social impact assessments.
  • Legal, tariff and contract structuring, including power purchase agreements.
  • Financial modelling and transaction advisory.
  • Early development equity that takes the first risk.

Direct application windows versus institutional allocators

The most important distinction is who can apply. Some facilities accept proposals directly from private developers, often through open calls or rolling portals — examples include EU ElectriFI, the AfDB-managed Sustainable Energy Fund for Africa (for eligible projects), EEP Africa and IFC InfraVentures, which co-develops projects as an early equity partner.

Others only work through governments, accredited entities or partner banks. The Green Climate Fund's preparation facility, the Climate Investment Funds and many multilateral trust funds fall into this group. For these, the route in is the national focal point, an accredited entity or the development bank leading the programme — not a direct application.

For developers in developing countries

Expect to bring something to the table: land rights or a site agreement, early government support, a credible sponsor team and a share of the cost. Grants rarely fund 100% of preparation. Many facilities also want to see how the prepared project will reach financial close, so name the likely lenders early.

For developers and advisors based in developed countries

International developers, engineering and advisory firms can access several preparation sources, sometimes with a home-country link. The US Trade and Development Agency funds feasibility studies and technical assistance that involve US firms; several European development finance institutions and export credit agencies support their own countries' companies in early development abroad.

Partnering with a local sponsor usually strengthens an application, and some facilities require it. Use the database to find facilities whose geography, sector and stage match the project, and check whether each one requires a local partner.

Common reasons applications are rejected

Screening teams see the same problems again and again:

  • Asking a preparation facility for construction money, or vice versa.
  • No clear path to revenue or to a paying buyer.
  • Weak sponsor track record without a stronger partner.
  • Project outside the facility's geography, sector or ticket size.
  • No evidence of government or regulatory support where it is needed.

Common questions

What is a project preparation facility?
A fund or programme that pays for the early work needed to make a project bankable, such as feasibility studies, impact assessments and legal structuring, before construction finance is raised.
Can private developers apply directly for project preparation funding?
Some facilities accept direct applications from private developers, often through calls for proposals. Others work only through governments, accredited entities or partner banks.
Can companies from developed countries get feasibility study funding?
Yes. Agencies such as the US Trade and Development Agency fund feasibility studies involving US firms, and several European institutions support their own companies' early development work abroad.
Do preparation grants have to be repaid?
Usually not, though some facilities use reimbursable grants or convertible instruments that are repaid or converted to equity if the project reaches financial close.
